# Executive Summary

There are 18 active and two inactive, 12.5 million gallon capacity , field

- constructed underground storage tanks (USTs) located at the Red Hill Bulk Fuel Storage Facility (RHSF). Previous environmental site investigations indicated a release had occurred and contaminated the groundwater underlying the RHSF

.
The United St ates (U.S.) Navy implemented a groundwater monitoring program, which includes collecting quarterly groundwater samples from U.S. Navy W ell 2254

- 01 (RHMW2254

- 01) and four groundwater monitoring wells (RHMW01, RHMW02, RHMW03 , and RHMW05 ) installed in the RHS F lower access tunnel. The U.S. Navy W ell 2254

- 01 is located approximately 3,000 feet downgradient from the RHSF and provides approximately 24 percent (%) of the potable water to the Pearl Harbor Water System (PHWS)

. The groundwater samples are analyzed for petroleum constituents and compared against State of Hawai ‘ i Department of Health (DOH) D rinking W ater Environmental Action Levels (EALs ) (DOH, 200 9 ).
In response to increasing concentration s of chemicals of potential concern (COPC s ) in the groundwa ter monitoring wells within the facility (specifically RHMW02) during 2008, plans were made to conduct four quarterly monitoring event s starting in August 2009 and ending in April 2010 at the following outside (non

- tunnel) monitoring well locations :

• RHMW04 ;

• Oily Waste Disposal Facility M onitoring W ell 01 (OWDFMW01) ; and

• H ā lawa Deep Well 2253

- 03 ( HDMW2253

- 03).

The four consecutive quarterly monitoring event s indicated that all COPC concentrations were below the EALs for samples collected at monitoring well RHMW04 . In January 2010
, concentrations of total petroleum hydrocarbons ( TPH ) diesel range organics ( DRO ) were above the EALs at OWDFMW01 and HDMW 2253

- 03 . As a result, quarterly monitoring was discontinued at RHMW04 and continued at the two remaining outside monitoring wells

. T his groundwater monitoring report presents the analytical results for samples collected on January 2 4
, 201 2 at the two outside monitor ing wells ( OWDFMW01 and HDMW2253

- 03 )

. Laboratory analytical results indicate that a ll COPC concentrations during the January 2012 monitoring event were below the EALs

. Dissolved lead was detected at estimated concentration s of 0. 20 μ g/L in monitoring well OWDFMW01 , and 0. 1 9 micrograms per liter ( μ g/L) in monitoring well HDMW2253

- 03

. Benzene was detected at an estimated concentration of 0. 70 μ g/L in monitoring well OWDFMW01

. All other COPCs were not detected at or above the limits of detection (LODs) or the limits of quantitation (LOQs). LODs and LOQs were below the EALs for all the COPCs . In the case where an EAL for a specific COPC is less than the LOQ, it is generally acceptable to consider the LOQ in place of the EAL (DOH, 2009). The results of this groundwater monitoring event indicate that concentration s of COPCs detect ed within the facility are not impacting these two outside monitoring wells.Quarterly Groundwa ter Monitoring Report

. This groundwater monitoring event is considered supplemental to the quarterly groundwater monitoring program conducted within the tunnels of the RHSF. This supplemental groundwater monitoring was conducted in response to increasing concentration s of COPCs in a groundwater monitoring wel l within the RHSF, specifically RHMW02
, during the October 2008 groundwater monitoring event

. The field activities performed for the January 201 2 quarterly groundwater monitoring event were conducted in accordance with the procedures described in the Work Plan
, Long

- Term Monitoring, Red Hill Bulk Fuel Storage Facility, Pearl Harbor, O‘ahu, Hawai‘i (Environet, 2010).


## 1.1 Project Objective

The groundwater monitoring was performed to evaluate the presence of COPCs in groundwater surrounding the RHSF. The groundwater monitoring was conducted to ensure that the DON remains in compliance with DOH UST release response requirements as described in Hawai ‘ i Administrative Rules (HAR) 11

- 281 Subchapter 7, Release Response Action.


## 1.2 Background

The U.S. Navy imple mented a groundwater monitoring program, which includes collecting quarterly groundwater samples from U.S. Navy W ell 2254

- 01 (RHMW2254

- 01) and four groundwater monitoring wells (RHMW01, RHMW02, RHMW03 , and RHMW05 ) installed in the RHSF lower access tunnel. The U.S. Navy W ell 2254

- 01 is located approximately 3,000 feet downgradient from the RHSF and provides approximately 24 % of the potable water to the PHWS

. The groundwater samples are analyzed for petroleum constituents and compared against DOH Drinking Water EALs (DOH, 200 9 ).
In response to increasing concentration s of COPCs in the groundwater monitoring wells within the facility (specifically RHMW02) during 2008, plans were made to conduct four quarterly monitoring event s starting in August 2 009 and ending in April 2010 at the following outside (non

- tunnel) monitoring well locations:

• RHMW04;

• Oily Waste Disposal Facility Monitoring Well 01 (OWDFMW01) ; and

• Hālawa Deep Well 2253

- 03 (HDMW2253

- 2 The four consecutive quarterly monitoring event s indicated that all COPC concentrations were below the EALs for samples collected at monitoring well RHMW04. In January 2010 concentrations of TPH

- DRO were above the EALs at OWDFMW01 and HDMW2253

- 03. As a result, quarterly monitoring was discontinued at R HMW04 and continued at the two remaining outside monitoring wells . T his groundwater monitoring report presents the analytical results for samples collected on January 2 4
, 201 2 at the two outside monitor ing wells (OWDFMW01 and HDMW2253

- 03). The following sections provide a description of the site and information on the RHSF and USTs.



### 1.2.1 Site Description The RHSF is located on the island of O ‘ ahu, Hawai ‘i, approximately 2.5 miles northeast of Pearl Harbor in H ā lawa Heights (Figure 1

- 1) . Land adjacen t to the north of the RHSF is occupied by the H ā lawa Correctional Facility and private businesses. Land to the south and west of the facility includes the Coast Guard Reservation and other residential neighborhoods . Moanalua Valley is located east of the facility ( Environet, 2010 ).
The Navy Public Works Department operates a potable water infiltration tunnel approximately 1,550 feet hydraulically downgradient from the RHSF ( Environet, 2010 ). The U.S. Navy W ell 2254

- 01 is located approximately 3,000 feet downgradient (west) of the RHSF and provides approximately 24 % of the potable water to the PHWS , which serves approximately 52,200 military consumers ( The Environmental Company, Inc. ( TEC ) , 2008).



### 1.2.2 Facility Information
The RHSF consists of 18 active and two inactive USTs operated by the United States Naval Supply Systems Command (NAVSUP) Fleet Logistic s Center (FLC) Pearl Harbor. Each UST has a capacity of 12.5 million gallons. The RHSF is located approximately 100 feet above the basal aquifer ( Dawson Group, Inc. , 2006)

. In 2002, the U.S. Navy installed a groundwater monitoring well (RHMW01) into the basal aquifer, directly down

- gradient from the RHSF, within the lower access tunnel. Groundwater samples from this well indicated that petroleum from the RHSF has migrated to the basal aquifer (AMEC Earth and Environmental, Inc., 2002). In 2005, the U.S. Navy began quarterly monitoring of the aquifer to protect their down

- gradient drinking water resource associated with the U.S. Navy Well 2254

- 01.
By Septe mber 2005, the U.S. Navy had installed two more groundwater monitoring wells (RHMW02 and RHMW03) within the RHSF UST system, a groundwater monitoring well (RHMW04) north of the RHSF (adjacent to the U.S. Navy Firing Range), and a groundwater monitoring wel l within the U.S. Navy Well 2254

- 01 infiltration gallery (RHMW2254

- 01). Since 2005, RHMW01, RHMW02, RHMW03, and RHMW2254

- 01 have been sampled quarterly for TPH

- DRO, TPH

- gasoline range organics (GRO), volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), and dissolved lead.
Due to increasing concentration s of COPCs at the groundwater monitoring wells within the RHSF (specifically RHMW02) during 2008, response measures were warranted. In April 2009, another groundwater monitoring well (RHMW05) was installed within the lower access tunnel@ A @ A @ A @ A @ A @ A @ A @ A

- 01.
Additionally, plans were made to sample three monitoring wells surrounding and outside of RHSF: RHMW04, OWDFMW01, and HDMW2253

- 03 (Figure 1

- 1 and Table 1

- 1). RHMW04 was installed to evaluate groundwater within t he basal aquifer upgradient from RHSF. OWDFMW01 (originally known as MW08) was installed into the basal aquifer in 1998 for a Phase II Remedial Investigation/Feasibility Study for the Red Hill Oily Waste Disposal Facility (Earth Tech, Inc., 2000). It is located geographically down

- gradient of the USTs and U.S. Navy Well 2254

- 01. HDMW2253

- 03 is controlled by the State of Hawai ‘ i Commission on Water Resource Management. HDMW2253

- 03 is located between the RHSF and the municipal drinking water supply well which is operated by the City and County of Honolulu Board of Water Supply (Hālawa Shaft Pumping Station 2354

- 01) (Figure 1

### 1.2.3 UST Information The USTs were constructed in the early 1940s. The tanks were constructed of steel and currently contain Jet Propellant (JP)

- 5 fuel, JP

- 8, and marine diesel fuel (F

- 76). Previously, several tanks stored Navy Special Fuel Oil, Navy Distillate, aviation gasoline, and motor gasoline. Each tank measures approximately 245 feet in height and 100 feet in diameter. The upper domes of the tanks lie at depths varying between approximately 100 feet and 200 feet below the existing ground surface (TEC, 2006).



### 1.2.4 Regulatory Updates During the summer and fall of 2008, DOH updated their EALs, which resulted in significant changes to the action levels associated with methylnaphthalenes. The drinking wa ter toxicity EAL for these compounds was 240 μg/L. This concentration presumed that methylnaphthalenes

were non

- carcinogenic. Evidence that they are human carcinogens has now been accepted by the U.S. Environmental Protection Agency (EPA). As a result, DOH adopted more rigorous EALs of 4.7 μg/L for 1

- methylnaphthalene and 24 μg/L for 2

- methylnaphthalene, corresponding to a residential tap water scenario, and a one in a million cancer risk (DOH, 2009). Also, the drinking water EAL for naphthalene was inc reased from 6.2 μg/L to 17 μg/L (DOH, 2009). Finally, the DOH Drinking Water EAL for TPH

- DRO was increased from 100 μg/L to 210 μg/L, although the DOH Groundwater Gross Contamination EAL for TPH

- DRO remains 100 μg/L.Quarterly Groundwater Monitoring Report

Due to the well construction characteristics of OWDFMW01 ( total depth of 142.8 feet below top of casing (bTOC)) and HDMW2253

- 03 ( large casing diameter o f approximately 12 inches from the top of casing to approximately 50 feet below the ground water surface
, and the well is open [not cased] from approximately 50 f eet bTOC to 1, 575 feet bTOC ), three well casing volumes were not purged prior to sampling. Instead, water was purged using disposable bailers until three

or more successive water quality parameter measurements had stabilized within 10 % . A Horiba ® U

- 22 multi

- parameter water quality meter was used to measure hydrogen activity (pH), temperature, specific conductivity, dissolved oxygen, turbidity, and oxidation reduct ion potential. R eadings were recorded on Groundwater Sampling Log data sheets (Appendix C )

. 

### 2.2.2 Groundwater Sample Collection
G roundwater samples were collected from OWDFMW01 using four

- inch and two

- inch disposable bailers directly into laboratory provided
, specially cleaned sample containers

. Groundwater samples were collected from HDMW2253

- 03 using a four

- inch double stop disposable bailer directly into laboratory prov ided, specially cleaned sample containers

. Due to the well construction characteristics of HDMW2253

- 03, a grab sample was collected at a depth below the solid casing (which extends about 50 feet below the water tab le) and within the open

- holed portion of the well. Dissolved lead samples collected from HDMW2253

- 03 required laboratory filtration due to the doublestop bailer required to collect the sample.Quarterly Groundwater Monitoring Report

### 2.2.3 Sample Management and Shipment Each sample container sent to the laboratory was assigned a project

- specific chain of custody identification number and a descriptive identification number. The sample identifiers provided specific data unique to each sample and were entered into the field notebook. The samples were labeled according to the procedures described in Procedure III

- E, Record Keeping, Sample Labeling, and Chain

- of

- Custody ( DON , 2007).
Following sample collection and labeling, the sample containers were packaged with bubble wrap and placed into individual Z ipLoc  bags, then immediately into insulated coolers with ice for preservation. The samples were shipped via FedEx to the laboratory on the same day of collection. The samples were managed under standard chain of custody protocol and documentation from c ollection to delivery to the laboratory. Sample handling, storage, and transport were performed according to the requirements described in Procedure III

- F, Sample Handling, Storage, and Shipping ( DON , 2007). 

## 2.3 Analytical Program
During the January 2 01 2 groundwater monitoring event
, two sets of primary groundwater samples, one set of duplicate groundwater sample s , and one set of quality control (QC) groundwater sample s were submitted to APPL, Inc. located in Clovis
, California

. Groundwater samples were analyzed for VOCs and TPH

- GRO by EPA Method 8260B, TPH

- DRO by EPA Method 8015B, PAHs by EPA Method 8270D SIM, and dissolved lead by EPA Method 6020

. The results of the laboratory analyses are presented and discussed in Section 3

. 

## 2.4 Field Quality Control Samples
Field QC procedures were followed to ensure viability and integrity of sample analytical data. Field duplicates were collected according to th e procedure s described in Procedure III

- B, Field QC Samples (Water, Soil) ( DON , 2007) and the Work Plan (Environet, 2010). Field duplicate samples were collected at a minimum of 10 % of primary samples and analyzed for the same COPC s

. Field rinsate samples were not required since disposable bailers were used.


## 2.5 Laboratory Quality Control Samples
Laboratory QC samples were analyzed as part of the standard laboratory QC protocols as presented in the Work Plan (Environet, 2010). Laborato ry QC for the groundwater monitoring event consisted of matrix spike (MS)/matrix spike duplicate (MSD) samples for organic analysis. Laboratory QC samples were collected and analyzed according to the procedure s described in Procedure III

- A Laboratory QC S amples (Water, Soil) ( DON , 2007). Laboratory QC MS/MSD samples are an aliquot (i.e., a subset) of the field sampl e ; t hey are not separate samples, but a special designation of an existing sample. Laboratory QC MS/MSD samples were analyzed for the same constituents as the standard samples. At a minimum, one MS/MSD sample pair was required per 20 samples, including duplicates.Quarterly Groundwater Monitoring Report

## 2.6 Equipment Decontamination

Decontamination of monitoring equipment was performed to en sure data quality, to prevent cross contamination, and to prevent the potential introduction of contaminants into previously

un

- impacted areas. Decontamination of monitoring equipment (i.e., Solinst water level meter and Horiba ® U

- 22 water quality meter) was conducted between monitoring locations according to the procedure s described in Procedure I

- F, Equipment Decontamination ( DON , 2007). Decontamination water generated at monitoring well OWDFMW01 was disposed of in the RHSF’s lower tunne l oil/water separator sump

. 

## 2.7 Investigation

# Section 3 Groundwater Analytical Results

This section provides a summary of analytical results for groundwater samples collected from the two outside monitoring wells on January 24 , 201 2

. Complete analytical laboratory reports are provided in Appendix D

. 

## 3.1 Summary of Groundwater Analytical Results

OWDFMW01
Dissolved lead was detected in OWDFMW01 at an estimated concentration of 0. 20 μ g/L which is below the Drinking Water EAL ( 1 5 μ g/L ) and the Gross Contamination EAL ( 5,000 μ g/ L ) (Table 3

- 1 , Table 3

- 2 )

. Benzene was detected in monitoring well OWDFMW01 at an estimated concentration of 0. 70 μ g/L which is below the Drinking Water EAL ( 5 μ g/L) and the Gross Contamination EAL ( 170 μ g/L)

.
No other COPCs were detected at or above the LODs and LOQs in OWDFMW01. All LODs and LOQs were generally below the EALs. In the case where an EAL for a specific COPC is less than the LOQ, it is generally acceptable to consider the LOQ in place of the EAL (DOH, 2009).

HDMW2253

- 03 Dissolved lead was detected in monitoring well HDMW2253

- 03 at a n estimated concentration of 0. 1 9 μ g/L which is below the Drinking Water EAL ( 15 μ g/L) and the Gross Contamination EAL ( 5,000 μ g/L) (Table 3

- 1 )

. No other COPCs were detected at or above the LODs and LOQs in HDMW2253

- 03

. All LODs and LOQs were generally below the EALs. In the case where an EAL for a specific COPC is less than the LOQ, it is generally acceptable to consider the LOQ in place of the EAL (DOH, 2009).



### 3.1.1 Data Quality Control Results
The laboratory quality control results were all within the control limits. The relative percent difference (RPD) of field duplicates for all analytes were within the 50 % criteria except lead

. The trip blank that accompanied the outside well samples did not c ontain detectable levels of any COPCs except for methylene chloride that was detected at an estimated concentration

. T he detection of methylene chloride in the trip blank does not affect the quality control process as the estimated detection level i s w ell below the Drinking Water EAL and the Gross Contamination EAL

. Th erefore
, t he data quality control results indicate that the data obtained for this monitoring event are suitable for their intended use (Table 3

- 2). 

## 3.2 Groundwater Contaminant Trend

- 2 were also not detected above the EALs during th is current groundwater monitoring event (January 2012)

.
TPH

- DRO concentrations in OWDFMW01 significantly decreased from Jan uary 2010 (1,490 μg/L ) to April 2010 (288 μg/L )

. The concentrations of TPH

- DRO at this monitoring well have decreased to non

- detect in the last six (October 2010, January 2011, April 2011, July 2011
, October 2011, and January 2012) consecutive monitoring event s (Table 3

- 3).

The c oncentration s of TPH

- DRO at HDMW2253

- 03 have decreased to non

- detect for eight consecutive groundwater monitoring events (Table 3

- 3).

The October 2010 detection of acetone at an estimated concentration below the DOH Drinking Water EAL w as the first at monitoring well OWDFMW01. Acetone was also detected at an estimated concentratio n in the trip blank sample

. This suggested that acetone was introduced to the samples during transport to and from the laboratory, and is not representative of groundwater at OWDFMW01. This conclusion was confirmed in the January 2011 , April 2011 , July 2 011
, October 2011 , and January 2012 monitoring event s as acetone was not detected in any of the samples collected

. The October 2010 detections of lead at concentrations below the DOH Drinking Water EAL were the first at these two monitoring wells (OWDFMW01 and HDMW2253

- 03). Lead was not detected in any of the samples in the January 2011 monitoring event or during Apri l 2011

. Estimated concentrations of lead below the DOH Drinking Water EAL were detected at both wells during th e July 2011 and October 2011 monitoring event s

. Lead was detected at estimated concentration s below the DOH Drinking Water EAL in monitoring well HDMW2253

- 03 and in monitoring well OWDFMW01 in this January 2012 monitoring event

. The January 2012 detections of lead at concentrations below the DOH Drinking Wate r EAL were the fourth at these two monitoring wells (OWDFMW01 and HDMW2253

- 03).

The January 2011 detection of benzene at an estimated concentration below the DOH Drinking Water EAL in OWDFMW01 was the first at this monitoring well. Benzene was detected at an estimated concentration in the duplicate sample collected from OWDFMW01 in April 2011; however it was no t detect ed in the July 2011 monitoring event. It was detected at an estimated concentration below the DOH Drinking Water EAL in HDMW2253

- 03 in the October 2011 monitoring event

. During the January 2012 monitoring event, b enzene was detected at an estimated concentration of 0.70 μ g/L in monitoring well OWDFMW01 which is below the Drinking Water EAL ( 15 μ g/L)
, and the Gross Contamination EAL ( 5,000 μ g/ L ) (Table 3

- 1
, Table 3

- 2 ).
The April 2011 detections of x ylenes and toluene in OWDFMW01 were the first at these monitoring wells. Xylenes and toluene were no t detect ed in the July 2011 and the October 2011 monitoring event s . Xylenes and toluene were not detected during the January 2012 monitoring event (Table 3

4.1 Summary

Dissolve d lead was detected at estimated concentration s of 0

. 20 μ g/L and 0. 19 μ g/L in monitoring well s OWDFMW01 and HDMW2253

- 03 , respectively
, during th e January 2012 groundwater monitoring event

. Th ese concentration s are below both the DOH Drinking Water EAL ( 1 5 μ g/L)
, and the DOH Gross Contamination EAL ( 5,000 μ g / L )

. Benzene was detected at an estimated concentration of 0. 70 μ g/L in monitoring well OWDFMW01 , which is below the DOH Drinking Water EAL (5 μ g/L )
, and the DOH Gross Contamination EAL (170 μ g/L ). No other COPCs were detected in monitoring wells HDMW2253

- 03 and OWDFMW01 during the January 2012 monitoring event

. 

## 4.2 C onclusions
Concentrations of PAHs and VOCs were previously not detected above the EALs during the August 2009, October 2009, January 2010, April 2010, July 2010
, October 201 0
, January 2011, April 2011
, July 2011 , and Octob er 2011 groundwater monitoring events. PAHs and VOCs were also not detected above the EALs during th e January 2012 monitoring event. The data continue to suggest that TPH

- DRO was the only COPC present in any notable quantity for the site ; however
, it has been non

- detect for at least the past six monitoring events

.
TPH

- DRO concentrations in OWDFMW01 significantly decreased from Jan uary 2010 (1,490 μg/L ) to April 2010 (288 μg/L )
, and were no t detect ed in the subsequent six monitoring event s ( Table 3

- 3 ). The c oncentrations of TPH

- DRO at HDMW2253

- 03 have decreased to

non

- detect able levels for the previous eight consecutive quarterly monitoring event s. The data suggest that TPH

- DRO concentrations in groundwater are attenuating naturally at the two outside wells

.
The October 2010 detection of acetone at an estimated concentration below the DOH Drinking Water EAL was the first at monitoring well OWDFMW01

. Acetone was also detected at an estimated concentration in the trip blank sample in October 2010

. Acetone was not detected in the subsequent f ive monitoring event s . This strongly suggests that acetone was introduced to the samples during transport to and from the laboratory. The October 2010 detection of acetone is not representative of groundwater at OWDFMW01.
The October 2010 detections of lead at concentrations below the DOH Drinking Water EAL

were the first at these two monitoring wells (OWDFMW01 and HDMW2253

- 03). L ead was not detected in any sampl es during the January 2011 monitoring event or during the April 2011 monitoring event

. Lead was detected at estimated concentrations below the DOH Drink ing Water EAL at both monitoring wells during the July 2011 monitoring event

. Lead was detected in monitoring well HDMW2253

- 03 at a concentration below the DOH Drinking Water EAL and in monitoring well OWDFMW01 at an estimated concentration below the DOH Drinking Water EAL during th e October 2011 monitoring event

- 03 at estimated concentration s below the DOH Drinking Water EAL duri ng th e January 201 2 monitoring event.

The January 2011 detection of benzene at an estimated concentration below the DOH Drinking Water EAL in OWDFMW01 was the first at this monitoring well. Benzene was detected at an estimated concentration in the duplicate sample collected from OWDFMW01 in April 2011; howev er it was not detected in the July 2011 and October 2011 monitoring event s . It was detected at an estimated concentration below the DOH Drinking Water EAL in HDMW2253

- 03 in the October 2011 monitoring event. B enzene was detected at an estimated concentration in monitoring well OWDFMW01 during the January 2012 monitoring event which is below both the Drinking Water EAL
, and the Gross Contamination EAL

. The April 2011 detections of xylenes and toluene in OWDFMW01 were the first at these monitoring wells. Xylenes and toluene were not detected in the July 2011 and the October 2011 monitoring event s . Xylenes and toluene were not detected during the January 2012 monitoring event. 

## 4.3 Recommendations

All COPC concentrations have been below the EALs for six and eight consecutive quarter ly monitoring events for samples collected at monitoring wells OWDFMW01 and HDMW2253

- 03, respectively. Reduced frequency of sampling from quarterly to annual groundwater monitoring of both monitoring wells is recommended.Quarterly Groundwater Monitoring Report
